Abstract: Disclosed herein are exemplary medical devices for controlled delivery of material compositions, particularly occlusive, therapeutic, or diagnostic compositions. Medical devices disclosed herein comprise components for maintaining a stationary position, for providing catheters at a precise step in a method, for inflating or deflating a balloon, if present, and for providing a composition to a target site.

Abstract: Disclosed herein are exemplary medical devices for delivery of compositions to a target site. A disclosed medical device may comprise a delivery device comprising a delivery device comprising a handle, a composition delivery container and its plunger, an insertion tube, a dual lumen catheter comprising an exit port and optionally, an end structure, and fluid connections therefor, components for moving one or more catheters or for compressing one or more catheters. Methods of treatment and diagnosis using a disclosed delivery device, compositions for such methods and kits and systems are also disclosed.

Abstract: Disclosed herein are exemplary medical devices for controlled delivery of material compositions, particularly occlusive, therapeutic, or diagnostic compositions.

Abstract: Disclosed herein are exemplary medical devices for delivery of compositions. Medical devices disclosed herein comprise components for the intake of one or more compositions through one port so that little to none of the composition is lost within the device because the composition is then delivered out the same port throughwhich the composition was drawn into the device.

Abstract: The present invention disclosed exemplary variably lockable syringe assemblies, methods of making and using the same. Such syringe assemblies can be used in multiple medical, surgical, veterinary and research applications. A syringe assembly disclosed herein may dispense a dose of a composition one or more times by locking and unlocking the plunger.
